Did you ever, as a teenager, look in the mirror and focus on all the bits of your body you really didn't like?
Everything would be better - perfect, even - if those bits were slimmer, narrower, smaller, perter.
In return for their agreement to be photographed, Yeo helped look after her subjects who needed assistance in the days following their procedures.
The pictures, although perhaps not for the faint-hearted, are compelling and eye-opening. If you ever thought happiness could be achieved through replicating Jennifer Lawrence's nose or Kerry Washington's smile, they might make you might think twice before changing what you've got.
The interesting thing about these pictures is they shed light on part of the plastic surgery process rarely seen.
Changing our bodies and appearance is such an accepted part of Western culture these days, what you actually have to put your body through to get bigger breasts, a different nose or smaller waist can be forgotten.
Personally, I can see why these women endured the pain, the uncertainty and the chance of disappointment that comes hand-in-hand with plastic surgery. I was one of those teenagers who pulled at her hips, dreamed of higher cheekbones, longed for a better chin.
Would I still jump at the chance to change my body in such a dramatic way, 13 years on? I'm not sure, but I'm really glad I've seen these pictures.
